Linux kernel sangathe kuthana ndi zochitika zosakumbukika bwino

Pa mndandanda wamakalata a Linux kernel adakwezedwa Vuto pakuthana ndi vuto la kukumbukira ku Linux:

Pali nkhani yodziwika yomwe yavutitsa anthu ambiri kwa zaka zambiri ndipo imatha kupangidwanso pasanathe mphindi zochepa pa Linux kernel 5.2.6 yaposachedwa. Ma parameter onse a kernel amaikidwa kukhala okhazikika.

Masitepe:

• Yambani ndi chizindikiro "mem = 4G".
• Zimitsani chithandizo chosinthira (sudo swapoff -a).
• Timatsegula msakatuli aliyense, mwachitsanzo, Chrome/Chromium ndi/kapena Firefox.
• Timayamba kutsegula ma tabo ndi masamba ndikuwona momwe kuchuluka kwa kukumbukira kwaulere kumachepera.

Zikangochitika pomwe tabu yatsopano imafunikira RAM yochulukirapo kuposa yomwe ikupezeka, makinawo amaundana. Mudzakhala ndi vuto ngakhale kusuntha cholozera cha mbewa. Chizindikiro cha hard drive sichimayimitsa (sindikudziwa chifukwa chake). Simudzatha kuyambitsa mapulogalamu atsopano kapena kutseka omwe akuyendetsa pano.

Vuto laling'onoli limatha mphindi kapena kupitilira apo. Ndikuganiza kuti dongosololi siliyenera kuchita izi. Ndikuganiza kuti pali china chake chomwe chiyenera kuchitika kuti mupewe "kuzizira" kotereku.

Ndine wotsimikiza kuti ndizotheka kusintha magawo ena a sysctl kuti mupewe izi, koma china chake chimandiuza kuti izi zitha kukhala zosakhazikika kwa aliyense chifukwa ogwiritsa ntchito omwe si aukadaulo omwe amakumana ndi vutoli amangosiya kugwiritsa ntchito Linux ndipo sangatero. chisamaliro kuti mufufuze mayankho pa Google.

В ndemanga pa Reddit, ogwiritsa ntchito ena amalimbikitsa kusinthana, koma izi sizithetsa vutoli, zimangoyimitsa ndipo nthawi zambiri zimakulitsa. Monga njira yothetsera mtsogolo, zowonekera mu kernel zitha kuphatikizidwa 4.20 ndi bwino kwenikweni 5.2 PSI (Pressure Stall Information) subsystem, yomwe imakulolani kusanthula zambiri za nthawi yodikira kuti mulandire zinthu zosiyanasiyana (CPU, memory, I/O). Dongosolo laling'onoli limapangitsa kuti zitheke kukonza kuwunika kwa kuchepa kwa kukumbukira koyambirira, kudziwa komwe kumayambitsa mavuto ndikuthetsa ntchito zosafunika popanda kuyambitsa zovuta zowonekera kwa wogwiritsa ntchito.
